TO ALL WIIOM IT MAY CONCERN:

Be it known that I, DONALD MCINROY, ofthe city and State of New Yorlgihave invented and madea certain new and useful, Improvement in Means for Drying SkiraWire, Cf niltlnWebbing,.anfLsirnlltnarticles;A vand I do hereby declare the following to be a full,` clear, and exact description of the said invention, reference being had to the annexed drawing, making part of this specification, 'wherein- Figure 1 is a longitudinal section of my improved apparatus..

Figure 2 is a plan of a portion of the apparutus, and

Figurer? is a section longitudinally of thejournal of the hollow drying-cylinder inlargersize.

y Similar marks oi' reference denote the same parts.` i

My invention has for its object the drying of cords, webbing, skirt-wire or similar material after it has been sized` or dyed; and my invention consists-in a s eries of parallel pipes arranged in 's'lightlyinclined ranges, so that the material to be dried passes up and down, being interlaced between the pipes so as to make the apparatus' compact, and at the same time present a large amount oiheating surface for the fabi-ic to berdrawn over;

and I employ hollow heated cylinders, around which the fabric passes between one of the ranges of-heating pipes and the next, so ns to cause the article to he dried to remain in contact with and revolve the drying-cylinder,

and at the sometime the friction -o'f the fabric is lessened as it passes through theapparatus.

In the drawing, a is a vat containing sizing or dye; b b are guide-rollers, and cc compressing-rollers, to.

canse the penetration of the sizing or dye into the fabric; ol' d and e e are pairs of squeezing-rollers kept towards each other by springs or similar means to press out the surplus moisture from the fabric. The drying-apparatus is composed of a series of pipes ortubes,-z' each of which is formed of a attcned orvother suitable shape, and

smoothed upon the surface with which the material to bedx-ied comes in contact, and these drying-tubes z'z' are connected, as shown in' fig. 2, so as to be heated by'steam admittedV Vby the pipe or pipes as atjQand the water of condensation is to be drown oiin any well-known manner from the lowest parts. The rangos of the drying A Pipes nre to beplaced at an inclination, and Ihave shown them as supported between W- shaped frames gg. If

the pipes iz' stand in thccsarc plane, the material to be driedI passing alternately on opposite sides, as shownx will` have the amount of friction and pressure on reach surface, as it isfdrawnalong, that results from the anglx made by the fabricpassing alternately above and below the said pipes: but if they are in two planes the fabric maybe passed almost straight through between the pipes, only touching tlieni slightly on opposite sides. These drying pipes present a lurgedextent of heating surface for the fabric to come into contact withuand atA the same time the action is similar'to a smoothing-iron to giv'e a gloss to the surface, and evaporation progresses much more rapidly when passing into and out ofacontact vthan would be the caseiit` the vapors wereconiined within the fabric by continued contact with al heated surface. At the angles where the material cbnges direction in I#passing from one range ot' pipes z' to the next, I employ hollow cylinders c lc, each one of which is constructed as seen in iig. 3, so as .to be heated by steam. The cylinders l: ape each made with a hcllowjournal at each end,

as seenv at l, and these revolve in boxes m, where they are both lubricated and-packed lby packing introduced' als fn, and kopt tight byj-tho follower o. A pipe, p, is introduced through the box m and shaft or journal l, and' is made tight by gland or packingat g. The pipe p, at one end ofthe cylinder la, is made with a benddownwards;` 'nt at r, to receive and 'convey away the water of condensation `and keep they cylinder free, and the pipe p at the other endsimply passes suiiiciently into the hollow journal Z to supplytho steam."` I providefa'hand-hole, a, aindf"v cover in one end of cach of the hollow'drying-cyliiiders lc, sons to give access to the inside-ofthe cylinder in l case of any derangement of the steamer water pipes. The cords, skirt-wire, or other material may be guided;

, in its entrance to the machine by thc ruck t, and a roller, u, kept down by an adjustable spring pressure,may beV employed at the central cylinder k to nidfinpres`s`ing"a`d1 consolidating the fabric? In this drying-apparatus'-.

several cords, skirt-wires, or similarorticles'can bedrawn through themaehine at the' `same tithe, and come ont. dried, smoothed, and finished, and this is done with great rapidity, and the material is free to contract as it dries, whereas in, those machines where the material iswou'nd back and for'thouer cylinders or rollers the contraction indi-ying :omet mes pauses o, strain that is so great-as to, injure theniachiner What 'I ciu new@ desire to secure by Letters Patent, is

1. A series ofstelmdrying pipes, z'z', arranged in. vranges in the Arnnnnr specified, in combination with cylintlersjgpluced,between the ranges of' pipes, as and for the purposes sct fprth. A

2.. I cl'u1im;t'hl1axid-hole and cover s, in combination with the cylinder k, journal-box m, packngs n and q, :Lsg asehd i'or the purposes set forth.

`'In witness whereof I have hereunto set my signature this twentysixth day of July, A. D. 1866. l
